ADJUSTABLE PATTERN.

To all whom it may concern:

Be it known that I, JOEL TESSITORE, a citizen of the United States, residing Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Adjustable Patterns, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in patterns and more particularly to a pattern or mold capable of various adjustments and my object is to provide an improved movement in connection with the movable or adjustable portions of the pattern or mold.

A further object of the invention resides in providing a movement which will enable the movable portions to retain the same general form in their various adjusted positions.

A still further object of the invention resides in providing a device which is simple and durable in construction, inexpensive to manufacture and one which will be very efficient and useful in operation.

With these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawings forming a part of this application,.Figure 1 is a plan view of a pattern with the improved move ment applied thereto and disclosing the parts in retracted position. Fig. 2 is a similar view showing the parts in their extended positions. Fig. 3 is a vertical section through the device, as seen on line 33, Fig. 1. Fig. 4 is an enlarged section through one end of one of the sliding rods guiding the movable portions of the device with respect to the stationary portion thereof. Fig. 5 is an enlarged perspective view of a detail of the movement. Fig. 6 is a fragmentary side elevation of the pattern showing the relation of the movable parts of the device with respect to one another when disposed to their extended positions. similar view of a slightly modified form of the invention. Fig. 8 is a horizontal section therethrough as seen on line 88, Fig. 7.

throughout the several views and in which 1 indicates an inner frame of irregular design, particularly adapted for use in connection with shoe machines. This frame consists of an outer vertical wall 2, taking the particular contour desired and a bottom 2 secured thereto. This frame, for convenience, will be termed a stationary frame. An outer complementary frame 2 is also provided which is composed of a plurality of wall sections 3, the ends of which are beveled, as shown at 4 and when said sections are brought together, so that the beveled ends contact with one another, the outer frame 2 will fit tightly around the inner frame 1. I have provided a means for the simultaneous movement of the sections of the outer frame 2, so that at all times said frame will take the general form similar to the inner frame 1, but of greater dimensions than the latter. To this end, I provide a plurality of eccentrics 5 which are pivotally mounted on the pivot pins 6, on the base or floor portion of the inner frame 1. These various eccentrics are pivotally connected together by means of the linking rods 7 and each eccentric has also pivotally connected thereto an additional linking arm 8.

\Vith the exception of two sections of the frame 2, which are compoundly curved, and indicated as 3 each of the sections 3 of said frame has an inwardly projecting rod or arm 9 carried thereon, which arms or rods are slidably disposed through openings 10 formed in the vertical wall of the inner frame 1 and adjustably connected with the inner end of each of the rods 9, is an eye bolt 11 which has pivotal connection with a linking arm 8 carried on the adjacent eccentric. These two sections 3 which were just referred to, as being compoundly curved and which are disposed on the upper portion of the frame 2, as indicated in the drawings, have removably secured thereto the shorter arms or studs 12 which extend through slots 13 in the adjacent portions of the outer wall of said inner frame 1. The inner ends of said studs or short arms 12 have pivotal connection with the inner ends Fig. 7 is a of the adjustable rods or linking arms 14, while the other ends of said rods or linking arms are pivotally connected, respectively, to two of the eccentrics 5, arranged in predetermined places within the frame 1.

Mounted on the floor or base of the frame 1, is an angular bracket or keeper 15, the

same being disposed directly between two l of the aforesaid eccentrics and a portion of this angular keeper or bracket 15 which 3 is spaced above the base or bottom, is longitudinally slotted, as shown at 16.

movably disposed in the slot 16 of said keeper 1:"), is a pin or bolt 17 to which are pivotally connected a pair of linking arms 18. These linking arms are also pivotally connected, respectively, to th adjacent eccentrics 5 hereabove referred to. is stated,

these arms 18 are pivotally connected to a pin or bolt 17, the latter being disposed through the slot 16 of the member 15 and in order to lock said pin or bolt in any of its adjusted positions, a nut 19 is provided for engagement with the lower threaded end of said pin or bolt.

From the above description of the construction of the device, it will be seen that as the pin or bolt 17 is moved in one direction, in the slot 16, the two adjacent eccentrics 5 which are connected to said pin by means of the linking members 18 will be swung on their pivots in one direction and in view of the linking rods 7, which connect all of the eccentrics together, it will be seen that all of said eccentrics will be swung on their pivots. lhe movement of these eccentrics on their pivots in one direction, will obviously draw in or force outwardly the case may be, the sections 3 of the outer frame 2, to which said eccentrics are connected, through the means licreabovc mentioned. The rods 9 connected to the sections 3 of the outer frame 2 will, of course, guide said sections in their movement inwardly and outwardly and it is obvious that in all positions of said sections 3, a complete outer frame will be formed which will take approximately the same design or contour as the inner frame 1, although in the extended position of said frame, the sections are themselves spaced from one another, as may be seen in Figs. 2 and 6 of the drawings. It will be seen, however, that in the movement of the sections of the outer frame with respect to the stationary inner frame, the two compoundly curved sections or those at the upper portion of the device, as indicated in Figs. 1 and 2 of the drawings, will move longitudinally of the wall. of the frame 1 and the slots 13 are provided to compensate for such movement. in order to aid in the guiding of the movement of the parts of the outer frame with respect to the inner frame, the additional guide rods 20 are removably provided on certain of the side sections of the outer frame which opcrate through openings 21 in the wall of the inner frame. When the pin 17 has been moved so that the outer frame has reached the desired size, said pin may be locked in its adjusted position by turning the nut 19 home thereon. The pattern is then complete and ready for use and it will be seen that the same capable of quick and ready ad justment to various sizes, as desired.

in Figs. 7 and S, I have shown a slightly modified form of the invention, wherein the wall sections 22 are provided, representing sections of an. outer frame, similar to the frame 2, which sections are designed for connection with one another throughout their movement. In carrying out this idea, each section is provided at its one end with a tongue 23 and at its other end with a groove 2 so that the tongue of one section may fit in the groove of the adjacent section and each tongue is provided with a slot 25. A pin 26 extends vertically through the slotted end of each of said sections to be disposed through the slot of the tongue inserted therein. and thus the sections are, at all times, connected together and are capable of movement with respect to one another.

As stated, in the objects of the invention, this device is particularly adapted for use in connection with shoe machines, but it will be understood that it may be used in any connection wlatsoever, wherein a form is desired and this particular movement which 1 have embodied in my invention will enable the form to be adjusted to various sizes desired. lVhile I have shown the form mov able outwardly, with respect to the stationary inner frame, it will be understood that the idea may be reversed, without changing the principle whatsoever.

From the foregoing it will be seen that I have provided a simple, inexpensive and etlicient means for carrying out the objects of the invention, and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.

It will also be seen that the traveling rods 9 and connecting links 8 are connected at the same degree as to the direction in which they have to travel and as to the centers 6 of the eccentrics. It will also be seen that the connecting rods of the eccentrics are connected all at the same degree as to the centers of the two eccentrics which are connected together thereby. It is this particular construction that sets forth the principle of this movement.

Having thus described this invention, what is claimed is 1. A pattern of the class described comprising a stationary frame of irregular design, a movable frame of similar design formed of a plurality of sections, means for simultaneously actuating the sections of the movable frame to move said movable frame to various posit-ions with respect to the stationary frame, and means for retaining said movable frame in any adjusted position.
